Network calls add 1,000-5,000x latency versus in-process function calls, resulting in 50-150% higher latency, 300% more resource usage, and 2-3x infrastructure costs. Benchmarks show microservices suffer from cascading failures (5x more downtime), database connection exhaustion, and serialization overhead. The article argues microservices solve organizational problems (team autonomy, independent deployment) rather than technical ones, and recommends modular monoliths for most applications. Microservices only make sense for organizations with 50+ engineers, independent scaling requirements, technology diversity needs, or compliance isolation. 435 39 2. 2 [](https://daily.dev/posts/my-2026-tech-stack-is-boring-as-hell-and-that-is-the-point--zw58f0sjv "My 2026 Tech Stack is Boring as Hell (And That is the Point)") Article DEV · 36w My 2026 Tech Stack is Boring as Hell (And That is the Point) A senior engineer advocates for choosing simple, proven technology over complex, trendy solutions. The author describes moving from microservices and Kubernetes to a monolithic architecture running on a single VPS with SQLite or Postgres, arguing that most applications don't need the complexity of distributed systems. The piece emphasizes that users care about working features, not architecture choices, and that boring, battle-tested tools allow developers to ship products faster while maintaining lower costs and cognitive overhead. 175 10 3. 3 [](https://daily.dev/posts/top-open-source-projects-that-will-dominate-2026-1byqjjqxd "Top Open Source Projects That Will Dominate 2026") Article DEV · 36w Top Open Source Projects That Will Dominate 2026 A curated list of nine open source projects predicted to gain prominence in 2026, including Biome (Rust-powered JavaScript toolchain), Bun (fast Node.js alternative), Deno 2.0 (TypeScript-first runtime), Zed (AI-enabled code editor), Turso (edge SQLite database), Ollama (local LLM runner), Ruff (Python linter), Astro (content-focused web framework), and Continue (open source AI coding assistant). The common themes are performance improvements through Rust rewrites, enhanced developer experience, and AI integration. 34 1 [See all DEV archives](/sources/devto/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/devto/best-of/2026/01#page","url":"https://daily.dev/sources/devto/best-of/2026/01","name":"Best DEV Posts — January 2026","description":"The most upvoted DEV posts from January 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/devto/best-of/2026/01#items","numberOfItems":3,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/microservices-are-killing-your-performance-and-here-s-the-math--oc7oxm66d","name":"Microservices Are Killing Your Performance (And Here's the Math)"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/my-2026-tech-stack-is-boring-as-hell-and-that-is-the-point--zw58f0sjv","name":"My 2026 Tech Stack is Boring as Hell (And That is the Point)"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/top-open-source-projects-that-will-dominate-2026-1byqjjqxd","name":"Top Open Source Projects That Will Dominate 2026"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"DEV","item":"https://daily.dev/sources/devto"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/devto/best-of"},{"@type":"ListItem","position":5,"name":"January 2026"}]}]} ```
